Comment 42 for bug 1308264

I have SOLVED the problem on my first cited machine (ASUS H81M-C motherboard) thanks to this page:
https://askubuntu.com/questions/1013830/slow-boot-long-kernel-load-time-due-to-wrong-resume-device?rq=1

This is the commands I used:

$ cat /etc/initramfs-tools/conf.d/resume
RESUME=UUID=ab61cdaf-a2a6-40bb-a787-9d383a4490af

But blkid shows that this partition does not exist anymore. I first think it was the swap partition I deleted some weeks ago, but the UUID does not correspond to the UUID I have commented in /etc/fstab. So I don't know where that UUID come from.

So I typed:
$ sudo vim /etc/initramfs-tools/conf.d/resume
and replace its content by:
RESUME=none

Then I typed:
$ sudo update-initramfs -u
$ sudo shutdown -r now

My SSD now boots very fast !
[ 2.814453] clocksource: Switched to clocksource tsc

[ 3.078411] EXT4-fs (sdb1): mounted filesystem with ordered data mode. Opts: (null)

I will post another message when I have access to the second machine to confirm if it solves also the problem.
